Lewcott PSR133 Phenolic Resin Conforms to MIL-DTL-64154

12 December 2010

Lewcott has responded to customer driven requests to retest and qualify its PSR133 phenolic to MIL-DTL-64154, rev. B, which has superseded MIL-R-9299, grade B.

Test samples of its PSR133 based prepreg were submitted to a leading independent test lab who tested and confirmed that the phenolic resin based prepregs conformed to the requirements of MIL-DTL-64154, Revision B. The test requirements included; room temperature and hot/wet tensile strength, room temperature, elevated temperature, hot/wet, and chemical/solvent conditioned flexural strength/modulus, and room temperature and hot/wet compression strength, as well as a variety of chemical/solvent conditioned change in weight and change in thickness requirements.

Carl Varnerin, Chief Technical Officer at Lewcott stated, We are very proud of the capabilities of our PSR133 Phenolic resin. Prepregs using this base resin have been used extensively in a wide range of demanding applications including armor/ballistics, carbon/carbon and ablatives, and aircraft interiors markets for many years. Since we specifically developed our phenolic resin for composite applications, we have the ability to target the properties of our phenolic resin for these end markets.

Michael Buck, President of Lewcott stated, Lewcott continues to be a leader in the development and supply of phenolic resins and phenolic matrix prepregs. We plan to continue to leverage our phenolic resin and prepreg expertise with our world class manufacturing to offer technically superior and cost effective products to the aerospace, military/defense and industrial markets. Lewcott is AS9100 and ISO 9001 certified.
